Description

(Claiming priority)
This patent document is filed on December 20, 2012 and claims the priority of US Provisional Patent Application No. 61 / 740,256, entitled “Column Connector System”, the entire contents of which are incorporated herein by reference. Quoted in the book.

  The present invention relates to a lift crane, and more particularly to a connector for connecting adjacent segments or parts such as columns used as a boom of a crane or the like.

  Large-capacity lift cranes generally have an elongated load bearing column structure, commonly used for booms, masts or jibs, having portions of the column members fixed with their ends abutting each other. Mainly, each column member is made of a plurality of cords, lacing members or elements of a lattice structure. At both ends of each cord, generally the same or different connectors are provided to fix the abutting column segments and support the compressive load between the abutting cords. A typical connector has one or more extensions and plates that are secured by pins that support a two-sided shear compressive load.

  For example, a foot boom consists of the end of a foot boom that is pivotally attached to the upper mechanism of the crane, and the top of the foot boom that is equipped with a sheave and is attached to lift and support the load. There is a boom member composed of five parts. One is about 3.05 meters (10 feet) long, the other is about 6.1 meters (20 feet) long, and the other three are about 12.2 meters (40 feet long). Feet). The boom has six boom segment connectors. In general, each segment has four cords and four connectors, making up a total of 24 connectors that must be aligned and pinned to assemble the boom.

  In general, a load supported by a boom member and consequently supported through a connector requires a protrusion, also called an extension, on a connector that is thick enough to withstand the load. To carry very heavy loads in high capacity cranes, a typical extension that is sandwiched between two plates and that provides a two-sided shear joint has a very large diameter to support compressive loads. Pins are required, resulting in very large connectors. Standard steel plates often do not have sufficient thickness to form extensions in connectors that are strong enough to support such loads. For example, a steel plate of about 7.8 tons per square centimeter (100,000 pounds per square inch) is obtained at a thickness of about 10 centimeters (4 inches) and is about 10 tons per square centimeter (13 per square inch). Ten thousand pounds of steel sheet is obtained at a thickness of about 7 centimeters (2.75 inches), both of which are insufficient in their own thickness to form a connector capable of supporting the maximum load. is there. Thicker and higher strength steel sheets are also available, but to obtain them usually requires a special order from the steel mill, with correspondingly high costs and lead times. As a result, the connector will generally be formed of cast steel to have sufficient thickness and strength.

  However, there are several problems in molding the connector, and the molding efficiency is poor. First, limiting the foundry, preparing the mold, and molding the connector is a time consuming and consequently expensive process. In fact, long lead times and sufficient work are put into place when preparing the mold before molding the first connector. If the production process is large enough, it would make sense to mold many connectors, but in terms of size and total number, the largest cranes with the largest connectors can only be produced in a small number. is there.

  In addition, due to the long molding lead time and high cost, the process can be used for work and design changes, as well as for use in prototype and destructive testing, or as a replacement part for one or a few parts. It cannot be easily adapted to manufacturing. In other words, as a manufacturing process, the connector molding process often cannot sufficiently respond quickly and appropriately to changing conditions and demands.

  Another disadvantage of molded connectors is that casting defects are not uncommon. As a result, molded connectors require finishing operations or machining to ensure that the connectors are within the specifications and tolerances required for a given application. This finishing operation is also often time consuming and expensive.

  As a result, there is a need for connectors that can be manufactured faster and easier than molded connectors.

  The column segment of the crane column includes a plurality of cords, each cord having a first end and a second end. The connector according to one embodiment is made from two or more metal plates.

  The first connector at the second end of the at least one cord includes n extensions. Here, n is a positive integer such as 1, 2, 3.

Each aspect so defined can be combined with any other aspect, unless specifically indicated otherwise. In particular, any feature indicated as a preferred point or advantage can be combined with any other feature indicated as a preferred point or advantage.

  For ease of reference, the designations “top”, “bottom”, “horizontal”, and “vertical” are used throughout the specification and claims, but generally refer to the ground or It refers to the position of the column part or boom part assembled in the vicinity. Although the boom can be lifted at different angles, including the vertical position, these designations can be applied.

  As shown in FIG. 1, the movable lift crane 10 has a lower mechanism, also referred to as a vehicle body 12, and a movable ground engaging member in the form of crawlers 14, 16. (Of course, there are two forward crawlers 14 and two rear crawlers 16, only one of which can be seen from the side view of FIG. 1) In the crane 10, the ground engaging member is a set. There may be only one crawler, ie one crawler on each side. Of course, other ground engaging members such as crawlers or tires added to the illustrated one can be used.

  The revolving structure 20 is connected to the vehicle body 12 using a roller path so as to be able to revolve, and can move around an axis with respect to the ground engaging members 14 and 16. The revolving unit 20 supports a boom 50 that is pivotally attached to a front portion of the revolving unit 20. The mast 28 is attached to the first end of the revolving structure 20, the rear connecting device 30 is connected between the mast 28 and the rear part of the revolving structure 20, and the movable counterweight unit 13 is mounted on the support member 33. A counterweight 34 is provided. The counterweight 34 may be formed by stacking a plurality of individual counterweight members on the support member 33.

  A boom hoist rigging device 25 between the top of the mast 28 and the top of the boom 50 is used to control the boom angle, move the load and load the load with the counterweight 34 suspended by a crane. To be used to balance. The hoist line 24 extends from the boom 50 and supports the hook 26. The swivel body 20 can also include other elements typically on a mobile lift crane, such as the operator's cab, hoist drum for the rigging device 25, and hoist line 24. If desired, the boom 50 may have a luffing jib that is pivotally attached to the top of the main boom or other boom structure. The rear coupling device 30 is coupled adjacent to the top of the mast 28. The rear coupling device 30 has a grid-like member designed to support both compressive and tensile loads as shown in FIG. In the crane 10, the mast 28 is installed at a fixed angle with respect to the swivel body during crane operations such as lifting, moving, and mounting operations.

  The counterweight unit 13 is movable with respect to the base of the revolving unit 20. In the embodiment of the crane 10, according to the inventions disclosed in US Pat. Nos. 7,546,928 and 7,967,158, each of which is the title of the invention “movable lift crane with various counterweights”. The counterweight unit 13 is designed to move in and out with respect to the front of the crane 10. A tension member 32 connected adjacent to the top of the mast 28 supports the counterweight unit 13. The counterweight moving structure 29 moves the counterweight unit 13 in front of or in front of the top of the mast 28 as shown by the solid line in FIG. 1, holds it there, and as shown by the dotted line in FIG. The revolving unit 20 and the counterweight unit 13 are connected so as to move and hold the second position behind the top 27 of the mast 28.

  In the crane 10, the counterweight moving structure 29 includes a hydraulic cylinder 36, a pivot frame 40, and a rear arm 38, and the counterweight unit 13 can be moved using these. (Similar to crawlers 14 and 16, the rear arm 38 actually has both left and right members, only one of which is shown in FIG. 1, and the pivot frame 40 has two side members, The hydraulic cylinder 36 has two cylinders that move in a vertical row, or one larger hydraulic cylinder or rack and power, preferably powered by four hydraulic motors, for linear drive. The pinion structure can be used instead of two hydraulic motors, and the pivot frame 40 can be made as a sturdy plate structure, and the two rear arms 38 can be a single structure. The pivot frame 40 is connected between the swing body 20 and the hydraulic cylinder 36, and the rear arm 38 is pivot pivot frame It is connected between the 40 and the counterweight unit 13. The hydraulic cylinder 36 is pivotally connected to the pivoting body 20 on a support frame 45 that lifts the hydraulic cylinder 36 to a position, and through the entire range of operation by the arrangement of the cylinder 36, pivot frame 40 and rear arm 38. The counterweight unit 13 can be moved. In this way, the rear arm 38 moves the counterweight unit 13 by the cylinder 36 when the cylinder 36 expands and contracts.

  The rear arm 38 has a sloped portion 39 at the end connected to the pivot frame 40. This allows the rear arm 38 to be directly connected to the side member of the pivot frame 40. The inclined portion 39 prevents the rear arm 38 from interfering with the side surface of the pivot frame 40 when the counterweight unit 13 is in the position indicated by the solid line in FIG.
